Carbon emissions 'outsourced' to developing countries Mon, 08 Mar 2010 00:00:00 EST Scientists report that over a third of carbon dioxide emissions associated with consumption of goods and services in many developed countries are actually emitted outside their borders. The study finds that, per person, about 2.5 tons of carbon dioxide are consumed in the US but produced somewhere else. For Europeans, the figure can exceed four tons per person. Most of these emissions are outsourced to developing countries, especially China.

Dirty air in California causes millions worth of medical care each year, study finds Fri, 05 Mar 2010 08:00:00 EST California's dirty air caused more than $193 million in hospital-based medical care from 2005 to 2007 as people sought help for problems such as asthma and pneumonia triggered by elevated pollution levels, according to a new study. While much work has been done previously to catalog the economic impact of air pollution across California, the study is the first to quantify the cost of hospital-based medical care caused by the dirty air.

Participation important for healthy marine parks Thu, 04 Mar 2010 05:00:00 EST The involvement of locals is a key ingredient in the success of marine parks which protect coral reefs and fish stocks. The largest-scale study to date of how coastal communities influence successful outcomes in marine reserves has found that human population pressure was a critical factor in whether or not a reserve succeeded in protecting marine resources -- but so too was local involvement in research and management.

Bringing bison back to North American landscapes Wed, 03 Mar 2010 14:00:00 EST The next 10 to 20 years could be extremely significant for restoring wild populations of American bison to their original roaming grounds. But for this to happen, more land must be made available for herds to roam free, government policies must be updated and the public must change its attitude towards bison, a new report says.

Where will the next food crisis strike? Extended geographical monitoring using satellite observation Wed, 03 Mar 2010 08:00:00 EST Satellite observation is the key instrument that will allow to double in 2010 the number of countries monitored in real time for detecting first indications of adverse agricultural outcomes. The new Integrated Phase Classification system facilitates and accelerates the reaction time to food security crises by allowing a common and internationally recognized classification of their severity.

Marine spatial planning: A more balanced approach to ocean management Wed, 03 Mar 2010 02:00:00 EST The old balkanized approach to ocean management, in which different resources and activities are governed by different laws and agencies, has failed to protect ocean ecosystems or reduce conflicts between ocean users, a panel of international scientists says. It should be replaced with a more balanced approach using marine spatial planning.

Strategic research program needed to determine whether, how past climate influenced human evolution Wed, 03 Mar 2010 00:00:00 EST Understanding how past climate may have influenced human evolution could be dramatically enhanced by an international cross-disciplinary research program.
